Abstract
Description
Le secteur technique de l'invention est celui des protections du matérielThe technical sector of the invention is that of material protections
situé sur des structures flottantes contre les agressions de la mer. Depuis quelques années on constate un fort développement des stabilisateurs de plate forme ayant pour conséquence une augmentation des agressions marines. Lorsque la mer est agitée, les vagues balayent le pont et peuvent endommager les équipements qui s'y trouve. Il existe déjà des dispositifs aptes à protéger ces équipements. Ainsi, des protections individuelles peuvent être prévues, chaque équipement étant recouvert d'un capot. Cette solution se révèle très peu pratique. En effet elle nécessite beaucoup de place, les protections devant se trouver à proximité de chaque équipement et beaucoup de located on floating structures against the aggressions of the sea. In recent years there has been a strong development of platform stabilizers resulting in an increase in marine aggressions. When the sea is rough, the waves sweep the deck and can damage the equipment there. There are already devices capable of protecting this equipment. Thus, individual protections can be provided, each item of equipment being covered by a cover. This solution turns out to be very impractical. Indeed it requires a lot of space, the protections must be near each equipment and a lot of
manipulations, la protection devant être manoeuvrée à chaque utilisation des éléments. handling, the protection having to be operated each time the elements are used.
Une alternative est le brise lames. C'est un écran fixe situé à l'avant du bateau ou sur une An alternative is the breakwater. It is a fixed screen located at the front of the boat or on a
face exposée d'une plate forme flottante. Les vagues viennent s'écraser sur ce dispositif. exposed side of a floating platform. The waves crash on this device.
Tous les équipements qui se trouvent derrière sont ainsi protégés. All the equipment behind it is thus protected.
Bien qu'il ne nécessite aucune manoeuvre, il présente plusieurs inconvénients. Le premier est le manque de visibilité pour les hommes se trouvant derrière cet écran. De plus cette protection contribue à l'augmentation de la surface équivalente radar. Cela augmente la détectabilité du bateau par les systèmes radars. Or, sur tous les bâtiments militaires Although it does not require any operation, it has several disadvantages. The first is the lack of visibility for the men behind this screen. In addition, this protection contributes to the increase in the equivalent radar surface. This increases the detectability of the boat by radar systems. Now, on all military buildings
modernes, on cherche a réduire cette surface équivalente radar. modern, we seek to reduce this radar equivalent surface.
Le but de la présente invention est de réduire les agressions marines sur les équipements exposés aux vagues des structures flottantes et de minimiser les manipulations ainsi que la The aim of the present invention is to reduce marine attacks on equipment exposed to waves from floating structures and to minimize handling as well as the
détectabilité radar du navire.radar detectability of the ship.
Pour ce faire l'invention a pour objet un dispositif d'atténuation des agressions marines pour une structure flottante comprenant au moins un panneau brise lames et caractérisé en To do this, the invention relates to a device for attenuating marine aggressions for a floating structure comprising at least one breakwater panel and characterized in
ce qu'il comporte des moyens aptes à modifier la position du panneau. which it comprises means capable of modifying the position of the panel.
Selon une caractéristique particulière, il est escamotable dans la structure flottante, cette dernière pouvant être le pont d'un bateau. According to a particular characteristic, it is retractable in the floating structure, the latter possibly being the deck of a boat.
Il peut être escamoté dans une fosse intégrée au pont. It can be retracted into a pit built into the deck.
Avantageusement le panneau pivote autour d'au moins un axe, la mise en mouvement est Advantageously, the panel pivots around at least one axis, the setting in motion is
réalisée par au moins un vérin qui peut être hydraulique ou électrique. produced by at least one jack which can be hydraulic or electric.
Le dispositif comporte au moins un talon de chape solidaire du panneau et au moins une The device comprises at least one clevis heel secured to the panel and at least one
butée.stop.
Ce dispositif présente l'avantage, en position escamotée, de ne pas prendre de place sur le pont. Tout le dispositif de commande tel que les actionneurs et les éléments mécaniques se trouve dans une chambre sous le pont. Il laisse ainsi une visibilité maximum aux hommes This device has the advantage, in the retracted position, of not taking up space on the deck. The entire control device such as the actuators and mechanical elements is located in a room under the bridge. It thus leaves maximum visibility to men
de bord. De plus, il offre une faible détectabilité radar. of edge. In addition, it offers poor radar detectability.
Lorsque la mer n'est pas agitée, le brise lame est escamoté, la surface équivalente radar de When the sea is not rough, the breakwater is retracted, the radar equivalent surface of
la structure flottante étant alors minimale. the floating structure then being minimal.
Lorsque la mer est agitée et que le brise lame est sorti, la surface équivalente de la structure est augmentée. Cependant, les vagues et la pluie forment un écran protecteur diminuant fortement l'efficacité des radars. Finalement, bien que la sortie du brise lame augmente la When the sea is rough and the breakwater is out, the equivalent surface of the structure is increased. However, waves and rain form a protective screen greatly reducing the effectiveness of radars. Finally, although the breakwater outlet increases the
surface équivalente radar, la détection du navire n'est pas facilitée. radar equivalent surface, detection of the ship is not facilitated.
De plus une seule action sur un commutateur permet la commande du dispositif. In addition, a single action on a switch allows the device to be controlled.
D'autres caractéristiques et avantages de l'invention apparaîtront dans la description Other characteristics and advantages of the invention will appear in the description
détaillée non limitative ci-dessous. Cette description est faite en regard des dessins detailed nonlimiting below. This description is made with reference to the drawings
annexés, parmi lesquels:annexed, among which:
- La figure I est la vue de dessus du brise-lames monté sur le pont d'un navire. - Figure I is the top view of the breakwater mounted on the deck of a ship.
- ILa figure 2 est la vue en coupe du dispositif en position escamotée. FIG. 2 is the sectional view of the device in the retracted position.
- La figure 3 est la vue en coupe du dispositif en position sortie. - Figure 3 is the sectional view of the device in the extended position.
Les figures I à 3 présentent un dispositif brise lames. Sur la figure I il est en position escamotée. Il est constitué de deux panneaux 3 et 4 formant un V, l'angle a entre eux étant Figures I to 3 show a breakwater device. In Figure I it is in the retracted position. It consists of two panels 3 and 4 forming a V, the angle a between them being
d'environ 135 . La surface 2 est le pont d'un bateau 12. about 135. Surface 2 is the deck of a boat 12.
Une fosse I est fixée au pont 2 par soudure. Les panneaux brise lames 3 et 4 sont reliés à une extrémité d'un vérin 5, comprenant une chambre inférieure 5a, une chambre supérieure b et un piston 6.Un talon de chape 7 est monté sur un axe de rotation 8. L'autre extrémité du vérin 5 est liée à la fosse 1 par l'intermédiaire d'une liaison pivot. Une butée fixe 9 est placée au fond de la fosse 1. La commande du vérin 5 est réalisée par une commande à A pit I is fixed to deck 2 by welding. The breakwater panels 3 and 4 are connected to one end of a jack 5, comprising a lower chamber 5a, an upper chamber b and a piston 6. A clevis heel 7 is mounted on an axis of rotation 8. The other end of the jack 5 is linked to the pit 1 by means of a pivot link. A fixed stop 9 is placed at the bottom of the pit 1. The actuator of the jack 5 is produced by a control with
distance 11 et un distributeur 10.distance 11 and a distributor 10.
Le fonctionnement du dispositif est le suivant. The operation of the device is as follows.
Le dispositif est, par mer calme ou peu agitée en position, escamotée comme sur la figure 2. Lorsque la mer devient agitée et que des paquets de mer viennent balayer le pont, la décision peut être prise de protéger les éléments du pont en sortant le brise lames. La commande à distance est alors activée et commande le distributeur 10 qui va orienter un flux d'huile (issu d'une centrale hydraulique non représentée) vers la chambre inférieure a. Le piston 6 est mis en mouvement. Il transmet un effort aux panneaux 3 et 4 qui se mettent à pivoter autour de l'axe de rotation 8 jusqu'à ce que le talon de chape 7 vienne en contact avec la buté fixe 9. Cette dernière reprend alors les efforts transmis par les panneaux 3 et 4 par l'intermédiaire des talons de chapes 7. Le système est alors en position sortie comme montré sur la figure 3. Les vagues viennent se fendre contre les panneaux 3 et 4 La disposition en V de ces derniers permet une excellente évacuation de l'eau et la protection du matériel siaué derrière est ainsi assurée. La pression hydraulique est maintenue dans la chambre inférieure Sa tant que le dispositif brise lames est sorti. C'est en effet la force engendrée par le fluide hydraulique qui maintient le brise lames en position sortie lorsqu'une vague sc fend sur ce dernier. De plus comme l'huile est légèrement compressible elle va jouer un rôle d'amortisseur au moment du choc avec la vague. Un dispositif non représenté et de type connu protège les organes hydrauliques des The device is, by calm sea or little agitated in position, retracted as in figure 2. When the sea becomes agitated and that packets of sea come to sweep the bridge, the decision can be taken to protect the elements of the bridge by leaving the breakwater. The remote control is then activated and controls the distributor 10 which will direct an oil flow (from a hydraulic power station not shown) towards the lower chamber a. The piston 6 is set in motion. It transmits a force to the panels 3 and 4 which start to pivot around the axis of rotation 8 until the clevis heel 7 comes into contact with the fixed stop 9. The latter then takes up the forces transmitted by the panels 3 and 4 via the heels of the yokes 7. The system is then in the extended position as shown in FIG. 3. The waves come to split against the panels 3 and 4 The V-shaped arrangement of the latter allows excellent evacuation water and the protection of the material behind it is thus ensured. Hydraulic pressure is maintained in the lower chamber Sa as long as the breakwater device is out. It is in fact the force generated by the hydraulic fluid which keeps the breakwater in the extended position when a wave sc breaks on it. In addition, as the oil is slightly compressible, it will act as a shock absorber at the moment of impact with the wave. A device not shown and of known type protects the hydraulic members from
surpressions trop importante.too much pressure.
Lorsque la mer se calme, une action sur la commande à distance 1 1 permet de basculer la pression hydraulique sur la chambre supérieure 5b. Le dispositif est alors escamoté dans la When the sea calms down, action on the remote control 1 1 switches the hydraulic pressure on the upper chamber 5b. The device is then retracted into the
fosse 1. Les panneaux 3 et 4 et le pont du navire sont alors au même niveau. pit 1. Panels 3 and 4 and the deck of the ship are then at the same level.
Bien entendu, diverses modifications peuvent être apportées par l'homme de l'art au dispositif brise lames qui vient d'être décrit uniquement à titre d'exemple non limitatif, Of course, various modifications can be made by those skilled in the art to the breakwater device which has just been described solely by way of non-limiting example,
sans sortir du cadre de protection défini par les revendications annexées. without departing from the protective framework defined by the appended claims.
Ainsi on peut utiliser des vérins hydrauliques, pneumatiques, électriques ou tout autre So we can use hydraulic, pneumatic, electric or any other cylinders
